Hi, I know playbin2 and it works, indeed.
I'm trying to avoid to use it because I'll need to add a " videobalance 
saturation=0.0" in the pipeline and I don't know how to do that with 
playbin2.
Furthermore using filesrc allows me to change to another source easily 
(e.g. v4l2src).

I read the docs but I cannot find indication how to achieve that.
Thanks
Marco
